HEAD REST COVER FOR DENTAL CHAIRS Filed March 20, 1929 iPV/n y Z Rain 12R ATTORNEY INVENTOR} may r 1 .1:

This invention relates to improvements in pekad rest covers for dental chairs and the The primary object of the invention resides in a sanita head rest cover which may be applied to t e head rest of a dental chair and a ter one use of the same, it may be discarded and a clean one promptly substituted therefor to prevent t e spread of scalp diseases from one user to another. I am cognizant that various types of such covers have been placed upon the market but they have proven more or less inconvenient in applying and removing to and from a head rest which 1 tends todiscourage extensive use and the changing of the same after each use. Furthermore d'ifiiculty has been experienced in causing the covers to remain in a flat proper position when applied to ahead rest which 2 detracts from the neatness of the chair, and greatly adds to the discomfort of the user. I My invention aims to overcome these objections by providing a simple and practical cover for that type of head rest now commonly used on dental chairs and the like.

Another object of the invention is the provision of a head rest cover formed of a single piece of foldable material having separate attaching pockets for the reception of the two cushioned head rest members, and a seam or crease intermediate the pockets to cause the covering surfaces of the cover to assume a substantiall V-shape when in an applied position an which surfaces lie flat upon the head rest sections without wrinkling.

With these and other objects in view, the invention resides in certain novel construe tion andcombination and arrangement of v mv'rae E. BOTNEB, QF Y@, H. Y.

Figure 5 is an enlarged horizontal sectional view on the line 55 of Figure l.

Referring to the drawing by reference characters, the numeral '10 designates my 65 improved head rest cover in its entirety which is constructed of a single piece of foldable material such as linenor paper. The material is folded in a manner to provide a substantially oblong envelope open at one of its longitudinal edges. The closed corners of the cover are rounded or bevelled as at 11 for a purpose to be presently described. The envelope includes a front wall 12 and a rear wall 13, which-walls are fixedly connected together midway between their ends by transversely creasing the same together from the open longitudinal edge to the closed longitudinal edge as at 14, and assing stitching 15 through the four plies folded material 7 to provide a seam as clearly shown in Figure 5 of the drawing. The envelope cover is therefore divided centrall into two separate attachinpockets 16. an the rear walls of these poc ets are provided with slots 17 which 7 5 extend inwardly from the open edge. These slots are substantially midway between the closed sides of the respective pockets.

In the drawings, 1 have illustrated my I sanitary cover in use upon a dental chair head rest 18 which includes the usual shank 19 adapted to be inserted into the socket provided on the chair. The stem supports cross as 20 on which the two spaced cushioned head rest members 21 are adjustably mount ed, the backs of which are provided with attaching arms 22;. in applying a cover as herein described to the hea rest .18, the walls of thepoekets 16 are spread a art and the open sides of the pockets broug t down over the res ctive rest members 21 until the closed en s of the slots 17 engage the arms 22 of the said members. The weight of the crease or 1 seam 14 causes the cover to break downward between the head rest members whereby the cover assumes a substantial V-shape to com-' fortably receive the'head of a user in the crotch thereof. The pockets serve to pro er- 1y center the cover upon the head rest an retain the same in a flat condition thereon against the natural tendencies of a person in the shifting of their head from one position of linen or other fabric, the same'may be ,7 its ed es, the walls of sai laundered after each use, and if made of paper or other inexpensive material, the same may be thrown away after each use. By' this ractiee, a clean, cover can be used for each individual user of the chair which will prove lfihly" sanitary as the spread of scalp and t er skin diseases may be prevented.

While I have described what I deem to be the most desirable embodiment of my invention, it is obvious that many of the details may be varied without in any way do arting from the spirit of my invention, and ftherefore do not limit myself to the exact details of construction herein set forth nor to anythin than the whole of my invention limited only y the appended claims.

What is claimed as new is 1. A head rest cover for dental chairs an the like comprising an envelope of flexible material open alon one of its edges, and a transverse crease ividing the interior of said envelope into two. separate pockets, the rear walls of said pockets being provided with slots extending inwardly rom their pockets one on each side of such line of fold,

each of said pocketshaving a wall provided with an opemn for coaction with structural elements of the ead rest to assist in securing the cover thereon.

In testimony whereof I hereby aflix my signature.
